I own the game...
It's worth the price...
I'm to the point now that I can't get any further in the game...
Best advice is to conserve ammo as much as possible...
Seems you always need more than you have available...
Sneak, grab, and knock out the badguys as much as possible...
Some spots in the game you will need to shoot 2-3 guys multiple times to get to the next level...
I've gotten through the oil rig mission, and then to the CIA building mission where I got stuck...
You have limited time to get inside the building through a fan opening before the fan starts up...
Only problem is, you can't kill anyone when inside...
This means your unarmed...
I've been killed so many times by the guards, I finally gave up and said the hell with it...
I'm done...
I also recommend the game "MechAssault"...
Can't get to the end of that game either but it's cool as hell...
